  1. 1. Evaluation of liver and fur copper concentrations in dairy cows : in relation to dietary intake of copper and molybdenum

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Ida Hansen; [2023]
    Nyckelord :copper; copper status; dairy cow; fur; liver; molybdenum; ruminant;

    Sammanfattning : Koppar (Cu) har en avgörande roll i flera viktiga metaboliska funktioner och är en essentiell mineral för idisslare. Kopparbrist kan resultera i ett flertal problem som påverkar djurets hälsa och produktion, men även överutfodring av Cu kan resultera i allvarliga kliniska symptom på grund av ackumulering av Cu i levern.

    Författare :Maria Elisabeth Eklund; [2020]
    Nyckelord :chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

    Sammanfattning : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

  4. 3. Nutritional ecology of roe deer (Capreolus capreolus L.) and fallow deer (Dama dama L.) : a case study of the browser - grazer dichotomy

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Heidi Rautiainen; [2017]
    Nyckelord :nutritional ecology; rumen contents; forage selection; deer; Capreolus capreolus; Dama dama;

    Sammanfattning : Nutritional ecology implies the nutritional links between an animal and its environment. On an evolutionary time scale competition for food drives species formation by genetic adaptations to the environment and subsequent niche separation of species. LÄS MER

  5. 4. Hur inverkar olika andel vallfoder i utfodringen på produktion, hälsa och beteende hos mjölkkor?

    L3-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Maria Solheim; [2007]
    Nyckelord :vallfoder; mjölkko; produktion; hälsa; beteende; kraftfoder;

    Sammanfattning : Cows are ruminants and they need fibers in their feed and sufficient eating time to function psychologically and physiologically. Many of our cows don't get enough forage and too much concentrates, which given in the wrong way may cause health and behavior problems. LÄS MER
